/* Puna's stylesheet. Hand-written, no build step, no dependencies.
 *
 * The design doc said "hand-written CSS committed alongside its sass". There is no sass and there
 * should not be: this is one file that a compiler would not make shorter, in a project that
 * deliberately has no npm. Plain CSS is the whole toolchain.
 *
 * --- THE CLASS NAMES ARE THE SPEC ---------------------------------------------------------------
 * Every selector here matches markup that already existed. The templates were written with semantic
 * class names from M3 onward and styled by nothing; this file fills that in without touching a
 * single template, which is why it can be reviewed on its own.
 *
 * --- BOTH THEMES, BECAUSE THE PAGE ALREADY PROMISED BOTH ------------------------------------------
 * `color-scheme: light dark` was the one real declaration in the placeholder this replaces, so the
 * browser has been painting form controls and scrollbars for whichever theme the reader prefers.
 * Dropping it now would break dark mode for people it currently works for. Colors go through
 * `light-dark()` on custom properties, so there is one palette with two values each rather than a
 * media query duplicating the rules.
 *
 * --- WHAT THIS IS NOT ------------------------------------------------------------------------------
 * Not a design system. Puna's pages are forms, tables and one address; the job is legibility and
 * hierarchy, not a look. Anything that needed a class the templates do not already have was left
 * alone rather than given one.
